POLYMER LIGANDS THAT CAN REGULATE REACTION TEMPERATURE IN SMART CATALYSTS

abstract

• The effects of changing the microstructure of a soluble polymer-bound catalyst in systems where the polymer acts to regulate the reaction through temperature induced phase separation are illustrated. In comparison with a lower molecular weight ligand with inverse temperature dependent solubility and a cationic rhodium(I) ligated by an amidobisdiphenylphosphine ligand, a higher molecular weight ligand with an alkyldiphenyphosphine end group and a neutral rhodium complex was more sensitive to temperature. Both types of soluble polymer-bound catalysts exhibited temperature dependent hydrogeneration activity and were active at low temperature (0C) and inactive at high temperature (room temperature or 50C, depending on catalyst and ligand).
